A Dutch Hip is a variation of a standard hip that has a small gable section at the
peak. The small gable can provide an attractive alternative to the standard hip
as well as provide room for additional ventilation. To calculate a Dutch Hip, Easy
Rafters essentially calculates a common rafter for the main roof and calculates
a 90º bay for the dutch hip section of the roof.

The Dutch Hip preview window displays a plan view, side view, and elevation view
of the dutch hip roof that reflects the actual dimensions of the roof and updates
as the dimensions are changed. The drawing pages display dimensioned side views
of the common, dutch common, dutch hip, and dutch center ledger rafters. A schematic
top view is included in the hip rafter drawing to illustrate the location of the
measuring line and the types of bevels required.

The Parts of a Dutch Hip Roof

Common Rafter
The common rafters extend perpendicular from the side wall of the building to the
peak of the main roof. The main roof common rafters will always be longer than the
dutch common rafters.

Dutch Common Rafter
The dutch common rafters extend perpendicular from the end wall of the building
to the center ledger of the dutch hip. If separate ledger boards are used dutch
common rafters also serve as the side ledgers that run from the side walls to the
ends of the center ledger.

Dutch Hip Rafter
The dutch hip rafters extend at a 45º angle from the outside corners of the building
to the joints between the side ledgers and center ledgers with their top edges flush
to the tops of the ledger boards. If separate ledgers are not being used, the location
of the ledgers should be marked on the end rafters of the main roof and then used
to locate the hip rafters.

Dutch Center Ledger
The dutch center ledger, if used, fits between the ends of the side ledger rafters.
If no ledgers are used, the location of the ledgers should be marked on the end
rafters of the main roof and the area of the center ledger should be filled in flush
to the face of the end rafters to provide a nailing surface for the dutch common
rafters.

Jack RaftersJack rafters extend perpendicular from the wall plates to the hip rafters.
The tail ends of the jack rafters are identical to the common rafters, but the top
plumb cuts have a single 45º bevel to frame against the hip rafters. Use the jack
rafter common differences listed on the hip rafter printout to determine the jack
rafter lengths.
